I'm using functions but using workers code (I asked if workers and pages are same, didn't know the code isn't interchangeable)

S

sumit•5/27/22, 9:18 PM

functions

I

Isaac McFadyen•5/27/22, 9:19 PM

Anything that runs in Workers can run in Functions.

I

Isaac McFadyen•5/27/22, 9:19 PM

They just have different APIs.

J

JamesOP•5/27/22, 9:20 PM

Yeah you can do almost all of the same stuff, but the syntax for how you export and run them is a little different. Functions uses file-based routing for example, whereas you're left to handle that yourself in a Worker

I

Isaac McFadyen•5/27/22, 9:20 PM

And even then you can use "Advanced Mode" to directly move code over if you wish.

J

JamesOP•5/27/22, 9:20 PM

Yeah what Isaac said

S

sumit•5/27/22, 9:21 PM

Sound awesome. Maybe I'm asking for too much but can I get some sort of 1-on-1 for a bit to get basics going for like 10 or 15 mins? I've been trying to use functions for long!

S

Stewart@Art.Page•5/28/22, 12:05 AM

Does anyone know when the functions limit is increased, should that reflect on the pages dashboard?
Spoke with Nevica yesterday and they said it'd be updated, but not sure if the UI stays the same or if it's still pending to go through

JamesOP•5/28/22, 12:06 AM

The UI does update, yes

It may take up to 24 hours for the actual usage counter to allow more than the default 100k though, if I recall

Ah okay, hopefully tomorrow mine will show x / <higher number> then, thanks!

if one were to do this but as a function in the /functions, I would need to convert the syntax and test it. anything else? https://github.com/cloudflare/templates/blob/main/examples/fast-google-fonts/fast-google-fonts.js

GitHub

templates/fast-google-fonts.js at main · cloudflare/templates

amorfati•5/28/22, 1:34 AM

or are these workers examples not applicable to /functions?

N

nitsky•5/28/22, 3:17 AM

Hey, is there support for rust+wasm in pages functions?

S

sumit•5/28/22, 10:14 PM

What's the equivalent of functions that is more google-friendly?

For example, in its early days, GitHub might not have been popular so it would have been better if you searched by mentioning git rather than GitHub on the search engine.

I

Isaac McFadyen•5/28/22, 10:18 PM

Cloudflare Functions, basically.

I

Isaac McFadyen•5/28/22, 10:18 PM

Or Cloudflare Pages but Pages didn't use to be dynamic so you'll get results for static sites mostly.

C

Chaika•5/28/22, 10:20 PM

or depending on what you're looking for, searching for cloudflare workers solutions (i.e "how to post a tweet using cloudflare workers"), and in most cases you can port the code over to functions. Probably would find a lot more code examples/etc that use CF Workers right now

IIsaac McFadyen Cloudflare Functions, basically.

S

sumit•5/29/22, 3:28 PM

Thanks, no equivalent outside CF ecosystem?

S

sumit•5/29/22, 3:29 PM

btw, is this code ok?

// Reacts to POST /api/hello
export async function onRequest(request) {
  // ...

  const body = { "products" : [
    { "Name": "Cheese", "Location": "Refrigerated foods"},
    { "Name": "Crisps", "Location": "the Snack isle"},
    { "Name": "Pizza", "Location": "Refrigerated foods"},
  ]}
  
  const headers = {

  };
  return new Response(body, { headers });
};

JamesOP•5/29/22, 3:38 PM

You'll want to

JSON.stringify

JSON.stringify

JSON.stringify

JSON.stringify the

body

body

body

body, but otherwise yes

JJames You'll want to `JSON.stringify` the `body`, but otherwise yes 🙂

S

sumit•5/29/22, 3:43 PM

Thanks, while sending (in this code) or while receiving?

I

Isaac McFadyen•5/29/22, 3:44 PM

Sending.

S

sumit•5/29/22, 3:44 PM

cool

I

Isaac McFadyen•5/29/22, 3:44 PM

You can't directly put an Object body into a response, you'll need to

JSON.stringify(body)

JSON.stringify(body)

JSON.stringify(body)

JSON.stringify(body)

S

sumit•5/29/22, 3:44 PM

so the new body will be this?
body = JSON.stringify(body)

I

Isaac McFadyen•5/29/22, 3:48 PM

Yup.

IIsaac McFadyen Yup.

S

sumit•5/29/22, 3:48 PM

also, what is the widest possible class of this code that I can google so that I can find reusable code?

JS functions? Node.js functions? What should give me reusable code while also ensuring max possible userbase?

S

sumit•5/29/22, 3:50 PM

i feel really awkward asking everything on this channel even though y'all are really nice

G

GregBrimble•5/29/22, 3:51 PM

“Pure JS” for the general day-to-day is usually what I search for. Or “web API” if I’m needing something specific about how to access request/response sort of stuff.

G

GregBrimble•5/29/22, 3:52 PM

The MDN docs are brilliant

S

sumit•5/29/22, 3:52 PM

yeah MDN is the MVP

S

sumit•5/29/22, 3:53 PM

so how would you have googled my previous question, for example?

I

Isaac McFadyen•5/29/22, 3:53 PM

Even some Node.JS stuff will work, as long as it doesn't import any node-js specific packages.

S

sumit•5/29/22, 3:53 PM

yeah pure js then i guess

Ssumit so how would you have googled my previous question, for example?

I

Isaac McFadyen•5/29/22, 3:53 PM

I would have done "return object in javascript response"

IIsaac McFadyen I would have done "return object in javascript response"

S

sumit•5/29/22, 3:53 PM

oh cool

I

Isaac McFadyen•5/29/22, 3:53 PM

an Object is what the

{key: value}

{key: value}

structure is called in JS.

S

sumit•5/29/22, 3:53 PM

cool

S

sumit•5/29/22, 3:53 PM

thanks

S

sumit•5/29/22, 4:00 PM

so if I want to get back my json on client side, what would you change in this code?

async function fetchProductsAsJSON() {
    const response = await fetch('https://mydomain.com/api/hello');
    // waits until the request completes...
    console.log(response);
  }

  fetchProductsAsJSON();

async function fetchProductsAsJSON() {
    const response = await fetch('https://mydomain.com/api/hello');
    // waits until the request completes...
    console.log(response);
  }

  fetchProductsAsJSON();

async function fetchProductsAsJSON() {
    const response = await fetch('https://mydomain.com/api/hello');
    // waits until the request completes...
    console.log(response);
  }

  fetchProductsAsJSON();

async function fetchProductsAsJSON() {
    const response = await fetch('https://mydomain.com/api/hello');
    // waits until the request completes...
    console.log(response);
  }

  fetchProductsAsJSON();

K

kian•5/29/22, 4:03 PM

const json = await response.json()

const json = await response.json()

K

kian•5/29/22, 4:03 PM

https://developer.mozilla.org/en-US/docs/Web/API/Response/json

Kkian `const json = await response.json()`

S

sumit•5/29/22, 4:05 PM

thanks and how would you have googled this if you were me?

K

kian•5/29/22, 4:06 PM

mdn response json

mdn response json

or

mdn fetch

mdn fetch

will both have it

Kkian `mdn response json` or `mdn fetch` will both have it

S

sumit•5/29/22, 4:06 PM

cool, thanks

K

kian•5/29/22, 4:06 PM

although in the context of code running in Workers or Functions, it's not 1:1 the fetch you'll see on MDN

K

kian•5/29/22, 4:06 PM

so there's https://developers.cloudflare.com/workers/runtime-apis/fetch/

Fetch · Cloudflare Workers docs

Documentation for Cloudflare Workers, a serverless execution environment that allows you to create entirely new applications or augment existing ones without configuring or maintaining infrastructure.

K

kian•5/29/22, 4:07 PM

it's like 90% the same but there's a few bits here and there that aren't in Workers

S

sumit•5/29/22, 4:07 PM

is there a porting guide?

The `addEventListener('fetch', event => {` syntax looks like a normal service worker Worker format -
